Grampa's pipes

Okay guys heres the deal. My grandfather has not smoked a pipe since the mid 50's. He just pulled these pipes out of nowhere. Four or five pipes in various conditions that I am dieing to smoke. I have no problem posting the pics of these pipes, but I wanted to know if anyone had any knowledge of old pipes, smoking them, and revitalizing them if need be. I have been wanting to smoke a pipe for a long time, and now that I have a few, I would like to know more about them. If anyone would like to see them let me know.
